Kostas Manolas and Edin Dzeko scored early goals for Roma to see off Qarabag 2-1 in Baku despite a much-improved performance from the hosts who reduced the deficit through Pedro Enrique's first-half strike.

1. Man United show their versatility

Once again Mourinho showed his great ability to adapt to the particular demands of different opponents, switching to a 3-4-3 formation to nullify the threat of CSKA and take command of the game from the start.

The formation saw United push up with Ashley Young and Daley Blind playing ostensibly as wingers, with few defensive duties to fulfil because of United's pressure on CSKA, the 68 per cent possession stat at half-time testimony to the dominance of the visitors.

2. Conte's clever in-game management

Chelsea were on top and creating several dangerous opportunities against a struggling Atletico before Diego Simeone decided something had to change.

The Argentine coach had lined up with a 4-4-2 but, seeing his side overrun in central midfield, tinkered and switched to a 4-3-3.

That pushed Angel Correa wide right and Yannick Carrasco wide left, looking to get in behind Chelsea’s advanced full-backs, and allowed Saul and Koke to try and shut down Hazard, who had been a constant thorn in the hosts’ side.

Atletico reaped almost instant dividends when Griezmann opened the scoring and Saul fired wide when he should have grabbed the second before half-time.

It led to a more even game, but Chelsea’s Antonio Conte responded to changing Fabregas’ position on the field to suit the team’s needs.

When Chelsea were chasing a goal he utilised the Spaniard as a quarter-back, behind Bakayoko and Kante, having started with the former as the deepest lying player.

Then, having got what he sought, he swapped them back, to keep the side tough for Atletico to break down.

3. Coutinho back on song

Plenty of us wondered how Philippe Coutinho would react to his proposed move to Barcelona falling through.

Would he sulk or would he knuckle down.

In the last two games, it has certainly been a case of the latter.

He was excellent against Leicester and notched his second goal in as many games to level the scores in Moscow.

With him in the team, Liverpool are just that bit more classy.

4. Kane hits his stride in Europe

Harry Kane's first-half opener made it four Champions League games in a row in which he has scored.

The only other English player to achieve that is Steven Gerrard and Kane is quickly becoming as important to his side as Gerrard was to his.

And it was another superb strike from the England man, composed as you like as he latched onto Alderweireld's pass and coolly slotted home.

It came at the perfect time - shortly before the break, with his side looking nervy against a very negative side.

That goal changed the game, but his quality shone through on his other two goals, as he netted a perfect hat-trick before leaving to standing ovation with 15 minutes left.

5. Fernandinho binding City's midfield

Fernandinho is City’s unsung hero, sacrificing himself for the team. He has the quality to play higher up the pitch, but happily plays the holding role to give the likes of de Bruyne and Silva licence to get forward.

He did it again and he shielded his defence, making a goal-saving tackle on Fred when City were under the cosh in the first half.

He was outstanding and gave City’s attacking talent the platform they needed with Shakhtar looking so impressive to make the breakthrough.

6. Iniesta wasted out wide

Ernesto Valverde was forced to watch Neymar walk away and then his replacement Ousmane Dembele limp off on his first league start.

The Barca boss's most recent answer? Floating in an unspecified diamond role.

That led to Iniesta being pushed wider and wider as the game went up - as the wing backs failed to bomb forward as expected.

The result was one half of the greatest midfield partnerships of a generation but wasted his evening drifting onto the left flank and lost his impact.

9. Bruised Bayern get tactics wrong

Bayern coach Carlo Ancelotti left both Arjen Robben and Franck Ribery out of his starting line-up for his side's second Group B match and questions will be asked of the Italian's decision after a comprehensive defeat.

The Germans, who enjoyed plenty of possession at Parc des Princes, lacked their usual clinical efficiency. But whether either offensive player would have made a difference against PSG's rapier counter-attacks is debatable.

Neymar, Cavani and man-of-the-match Mbappe were irresistible. The German champions never recovered after being stunned by Alves' early opener as PSG's star trio turned on the style at the Parc des Princes.

10. Celtic bounce back

Brendan Rodgers' side were humiliated in the opening week of the Champions League group stages. The Scottish champions took the full force of PSG's expensively assembled attacking line, losing 5-0 at home.

Two weeks later, though, and they have boucned back.

There will have undoubtedly been nerves as they travelled to Belgium but a 3-0 win over Anderlecht shows there has been no lasting damage.
